exhaust rear box for a t/d

[rutter123]

searching the net for rear box t/d hatch, seems a lot listed but confusing, would i be right in assuming there are basically 2 back boxes, flange and clamp type, and obviously length difference for hatch/estate, no one really lists a t/d rear box only listed as a 1.8 diesel, is this the same part to fit a t/d? a link would be good if anyone knows of the correct backbox to fit a 90 tzd turbo hatch. many thanx.

Indeed, TD and non turbo ARE different as the n/a are a smaller bore, a 1.9 TZi/GTi or 16v rear box will also fit your car.

have you tried Ebay?

This very subject, has been recently discussed in THIS thread

more confusion, have looked at more listings for rear box and td/gti listings use a flange type fitting, mine has regular clamp fittings,is this the norm for a t/d?

[mat_fenwick]

No. Maybe a 'bitsa'?

[Tim Leech]

They do use clamp to hold the two parts of the exhaust together, can you load a picture up?

Both the inlet and outlet on the crossbox should be flanged, while the joint between the front and intermediate pipes is a standard push in.

not flanged defo normal clamp type on the in/out of the mid box, according to s/h the full system was last replaced in 2004 with a bosal backbox and mid box, i have decided to change the whole system as its all pretty knackered and available from germany @ £66 + p/p.

have had a look under the gti and that has flange fittings but is a walker system, tho the same diameter pipework, i guess its all a bit mix/match and wotever they had on the shelf at the time. also appears my n/a tgd has the same bosal system as the tzdt fitted, where as the n/a diesels should have the smaller diameter pipework? the plot thickens.

Not sure whether the TD front pipe would fit the NA manifold - I welded the NA front pipe to the TD centre pipe on mine!

It could be that they didn't necessarily use the factory standard joints on your particular system - I've come across that before when a complete system has been fitted.
